idling issues

Hey everyone,

I'm having some idling issues with my tacoma. After driving for a little bit it will idle around 500 and shake and act like it's about to stall. Any suggestions or ideas of what's going on?

Thanks for the help!

 

Fuel pump or fuel filter?

 

I'm going to guess spark plugs or transmission TCC Solenoid (if it feels like it's not downshifting properly. I very well am probably wrong, though. When you accelerate from a stop does if shift fine from 1st to 2nd or does it feel like it starts out in 2nd?

 

Just replaced the fuel pump and that's when it started idling low. Do you think I need to run it a few cycles to see if it just disappears? It feels like it's shifting just fine. No problem there.

 

Did you disconnect the battery recently? It will take a bit to relearn if you did. It might be time for a tune-up and throttle body/MAF cleaning too, depending on your milage and service history.
